title: Folate deficiency presenting as pyrexia: a case report.
abstract: Folate deficiency is an uncommon cause of pyrexia. We describe the case of a 29-year-old male who presented with a pyrexial illness subsequently attributed to megaloblastic anaemia secondary to severe folate deficiency, after exclusion of other infective or inflammatory causes. A temperature chart documenting the course of the patient's pyrexia is presented and potential pathophysiological mechanisms are proposed. Folate deficiency is a reversible cause of pyrexia that should be considered in any patient who presents with a pyrexial illness of unknown cause.
